To all fwiom I? may concern; i

lina, have-invented cert-ain new and useful Improvements in an -Automobile Jack," of .f

which the' following is aspecilication.

.aThe present invention relates to l(if-vehicle jack adapted particularly for tilting an automobile in yorder that work may be con- An important object of .the-invention is to provide a jack of this nature formed in two .seotionsupon .which the automobile may be run and then operated to tilt ithe automobile to a convenient position.

Another important object of the invention isito'fprovideja j'ackofrthis nature with a tiltable platform for supporting the wheels of an automobile in order that said automobile may be tilted easily.

A still further important object of the invention is to provide a jacking structure of the nature specified which is possessed of a very simple and efficient structure, one which is thoroughly reliable in operation, inexpensive to manufacture, easy to manipulate, not liable to readily get out of order, strong, durable, light, and otherwise well adapted for the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing Figure 1 is a side elevation of an automobile showing the same situated on our improved jack structures,

Figure 2 is a front elevation of an automobile on one of the jack structures,

.Figure 3 is a top plan View o-f one of the jack structures,

Figure 4 is a detail section through one of the jack structures on an enlarged scale taken substantially on the line 4--4 of Figure 3, and

Figure 5 is a detail perspective of the base member.

Referring to the drawing in detail it will be seen that two jack structures are provided, one for the front wheels and the 18,4925. serial No1-10,008.

,other for therear-wheels of the automobile. The automobile isftobe driven on' these-jack structures. As both jack structures ...are

. idei'itical, 'al ,detailed description of one -will be sufficient to impartaclear understanding of both?. r .f n.451

The-jack, structure includes'L generally ya base memberA, a* platform B, and an operating mechanism supporting -frame C.

The' basezmembery A f vinclud'es=,a pairv of resilient bars 5` connected ato al cross iba-r 6I sow as@ to diverge therefrom, the freefends of `the bars 5 beingl apertured fais? ,glhe

. platform .-B- includes l ai pair Y of; longitudinally extending spaced parallel Emembers Sirprefgitudinal member 8, one adjacent each end member 9 so that the wheels of the automobile may be run up o-n the platform and the end transversely extending members 9 will prevent side slipp-ing thereof when the platform is tilted as is shown in Figure 2. Bolts or other suitable fastening elements 12 loosely connect one end member 9 with the extremities of the bars 5 so as to form a substantial hinge connection between one end i of the platform and one end of the base member, it being understood that these fastening elements pass through the apertures 7.

The frame C is of an inverted U-shaped formation to include a top rail 13 and side rails 14. The extremities of the side rails 14 are pivotally engaged with the ends of the longitudinal members 8 opposite to the ends supporting the member 9 hinged to the base member. A beveled gear 15 is journaled in the top rail 13 and has an internal' screw threaded bore for receiving a screw 16, the lower end of which is reduced and squared for reception in a squared opening 16 provided in the bar 6 so as to prevent turning of this screw. A bracket strip 18 is mounted in one corner of the frame C and a shaft 19 is journaled through one side rail 14 as at 2O and through the strip 18. The inner end of this shaft has fixed thereto a beveled gear 21 meshing with beveled gear 15 while the outer end thereof is squared as at 22 for the reception of a crank or the like 23.

From the above detailed description it will be'readily seen that when an automobile is run up onto the platforms B as in' l.e'rablyfin.the formof4 angle irons ,connted i bya plurality of- .f transversely ..'.0Xtend}ng members, 9, Y.and `cross braces; 10a @A fpar: 0f plates. 11i project ioutwardly fromsea'lriln- 15 will beallsed xtolli-eveil n pl thescrews 16, 5 Caryingrwith 'inne-'fr-mevo- @manie endH of the platform B pivoted thereto The end members 9 of the platform will prevent side skidding of the automobile fas it is being tilted. lVhen in this vtilted position ready l0 Aaccess may Abeiludbo-ilhe 'nnderiparts ofthe VThe looseI connection 'providedby the zbolts or'other:fasteningelements L2 Will'limit the 15 angle to which the platform B. niay bedis- :pos'edvinrelatioiinto thei'fbzrsefm'e'mber as,
